Method and system for registering events in wind turbines of a wind power system

Abstract

Methods of registering events in a wind power system comprising at least two data processors. The data processors of said wind power system are mutually time synchronized. Events are registered in said at least two data processors. The timing of said events registered in different of said at least two data processors is established according to said time synchronization. Events may be registered and preferably analyzed according to a common timing. The event analysis makes it possible to establish an analysis where events of different wind turbines are basically interrelated and where information regarding such interrelation may be important or crucial for establishment of control or fault detection based on correctly timed events from different wind turbines.

1. A wind power system comprising:
 a master clock; 
 a first sensor configured to generate first event data from an event occurring in the wind power system; 
 a second sensor configured to generate second event data from the event occurring in the wind power system; 
 a first data processor including a first slave clock, the first data processor configured to communicate with the master clock for synchronizing the first slave clock to the master clock, to communicate with the first sensor to receive the first event data, and to time stamp the first event data in accordance with the slave clock to generate first time stamped event data; 
 a second data processor including a second slave clock, the second data processor configured to communicate with the master clock for synchronizing the second slave clock to the master clock, to communicate with the second sensor to receive the second event data, and to time stamp the second event data in accordance with the slave clock to generate second time stamped event data; and 
 an event information analyzer configured to receive the first and second time stamped event data from the first and second data processors, the event information analyzer configured to analyze the first and second time stamped event data for correlating the first time stamped event data with the second time stamped event data in the time domain to determine if the first event data and the second event data are related to a common triggering event. 
 
     
     
       2. The wind power system of  claim 1  wherein each of the first and second data processors includes a buffer configured to store the event data respectively communicated from the first and second sensors. 
     
     
       3. The wind power system of  claim 1  further comprising: a wind turbine that includes the first and second data processors.

       5. The wind power system of  claim 1  further comprising:
 a first wind turbine that includes the first data processor; and 
 a substation that includes the second data processor. 
 
     
     
       6. The wind power system of  claim 1  wherein the first and second data processors include at least one wind turbine controller. 
     
     
       7. The wind power system of  claim 1  wherein the master clock is an internal clock of the wind power system. 
     
     
       8. The wind power system of  claim 1  wherein the master clock is an external clock to the wind power system. 
     
     
       9. The wind power system of  claim 1  further comprising:
 an earth satellite system receiver. 
 
     
     
       10. The wind power system of  claim 1  further comprising:
 a substation that includes the master clock.
